Changed paths:
M window-copy.c
Log Message:
-----------
Performance improvements for regex searching, most notably:
- Use the grid data directly instead of copying it.
- Special case the most typical one byte character cells and use memcmp
for multiple bytes instead of a handrolled loop.
- Hoist regcomp out of the loop into the calling functions.
GitHub issue 2143.

Use a comparison to check for wrap and avoid an expensive modulus.

M window-copy.c
Log Message:
-----------
Do not go down the regex search path (which is expensive because we need
to convert the grid data into a string for regexec and reverse it to
find the grid position) if the search string does not contain any regex
special characters.
