Vim 7.3:
- Included conceal patch.
- remove w:ownsyntax, automatically set w:current_syntax to the value of
- b:current_syntax after loading a syntax file.
- :ownsyntax only sets w:current_syntax.
+ HL disappears in other window:
+ :sp
+ :ownsyntax perl
+ :e
+ Documentation update:
+ remove w:ownsyntax, automatically set w:current_syntax to the value of
+ b:current_syntax after loading a syntax file. :ownsyntax only sets
+ w:current_syntax.
- using NSIS 2.46: install on Windows 7 works, but no "Edit with Vim" menu.
Use register_shell_extension()? (George Reilly, 2010 May 26)
