patch 9.1.1526: completion: search completion match may differ in case
Problem: completion: search completion match may differ in case
(techntools)
Solution: add "exacttext" to 'wildoptions' value (Girish Palya)
This flag does the following:
exacttext
When this flag is present, search pattern completion
(e.g., in |/|, |?|, |:s|, |:g|, |:v|, and |:vim|)
shows exact buffer text as menu items, without
preserving regex artifacts like position
anchors (e.g., |/\<|). This provides more intuitive
menu items that match the actual buffer text. However,
searches may be less accurate since the pattern is not
preserved exactly.
By default, Vim preserves the typed pattern (with
anchors) and appends the matched word. This preserves
search correctness, especially when using regular
expressions or with 'smartcase' enabled. However, the
case of the appended matched word may not exactly
match the case of the word in the buffer.

closes: #17667
