Hi everybody
If the option --from-here is specified, the resulting search by context is
always case-sensitive even if the option --ignore-case is present.
Example:
// will find your main function
global --from-here=25:/path/to/file.c main
// won't find your main function
global --from-here=25:/path/to/file.c -i Main
The attached patch fixes this issue.
Thank you & best regards
fabian
