René Scharfe ed40a0951c grep: support NUL chars in search strings for -F
Search patterns in a file specified with -f can contain NUL characters.
The current code ignores all characters on a line after a NUL.

Pass the actual length of the line all the way from the pattern file to
fixmatch() and use it for case-sensitive fixed string matching.
