- * This code was included to provide a portable vsnprintf() and snprintf().
- * Some systems may provide their own, but we always use this one for
- * consistency.
- *
- * This code is based on snprintf.c - a portable implementation of snprintf
- * by Mark Martinec <mark.martinec@ijs.si>, Version 2.2, 2000-10-06.
- * Included with permission.  It was heavily modified to fit in Vim.
- * The original code, including useful comments, can be found here:
- *	http://www.ijs.si/software/snprintf/
- *
- * This snprintf() only supports the following conversion specifiers:
- * s, c, d, u, o, x, X, p  (and synonyms: i, D, U, O - see below)
- * with flags: '-', '+', ' ', '0' and '#'.
- * An asterisk is supported for field width as well as precision.
- *
- * Limited support for floating point was added: 'f', 'F', 'e', 'E', 'g', 'G'.
- *
- * Length modifiers 'h' (short int) and 'l' (long int) and 'll' (long long int)
- * are supported.  NOTE: for 'll' the argument is varnumber_T or uvarnumber_T.
- *
- * The locale is not used, the string is used as a byte string.  This is only
- * relevant for double-byte encodings where the second byte may be '%'.
- *
- * It is permitted for "str_m" to be zero, and it is permitted to specify NULL
- * pointer for resulting string argument if "str_m" is zero (as per ISO C99).
- *
- * The return value is the number of characters which would be generated
- * for the given input, excluding the trailing NUL. If this value
- * is greater or equal to "str_m", not all characters from the result
- * have been stored in str, output bytes beyond the ("str_m"-1) -th character
- * are discarded. If "str_m" is greater than zero it is guaranteed
- * the resulting string will be NUL-terminated.

+ * This code was included to provide a portable vsnprintf() and snprintf().
+ * Some systems may provide their own, but we always use this one for
+ * consistency.
+ *
+ * This code is based on snprintf.c - a portable implementation of snprintf
+ * by Mark Martinec <mark.martinec@ijs.si>, Version 2.2, 2000-10-06.
+ * Included with permission.  It was heavily modified to fit in Vim.
+ * The original code, including useful comments, can be found here:
+ *	http://www.ijs.si/software/snprintf/
+ *
+ * This snprintf() only supports the following conversion specifiers:
+ * s, c, d, u, o, x, X, p  (and synonyms: i, D, U, O - see below)
+ * with flags: '-', '+', ' ', '0' and '#'.
+ * An asterisk is supported for field width as well as precision.
+ *
+ * Limited support for floating point was added: 'f', 'F', 'e', 'E', 'g', 'G'.
+ *
+ * Length modifiers 'h' (short int) and 'l' (long int) and 'll' (long long int)
+ * are supported.  NOTE: for 'll' the argument is varnumber_T or uvarnumber_T.
+ *
+ * The locale is not used, the string is used as a byte string.  This is only
+ * relevant for double-byte encodings where the second byte may be '%'.
+ *
+ * It is permitted for "str_m" to be zero, and it is permitted to specify NULL
+ * pointer for resulting string argument if "str_m" is zero (as per ISO C99).
+ *
+ * The return value is the number of characters which would be generated
+ * for the given input, excluding the trailing NUL. If this value
+ * is greater or equal to "str_m", not all characters from the result
+ * have been stored in str, output bytes beyond the ("str_m"-1) -th character
+ * are discarded. If "str_m" is greater than zero it is guaranteed
+ * the resulting string will be NUL-terminated.
+ */
