bug#15630: Acknowledgement (grep 2.14 much slower than 2.5.1)

[Z. Majeed]

I see the reason is the workaround in do_execute that turns on line-by-line 
matching for -i across the board - I got runtime confirmation by trying 
"<name>.*[rR][uU][sS][sS][iI][aA]" - the times were faster than for grep 2.5.1 
with -i:
3.59user 2.95system 0:06.55elapsed

I'm not sure if the workaround is for the -i problem in UTF-8 locales discussed 
in http://savannah.gnu.org/bugs/?29391. This bug report really should be titled 
"--ignore-case very slow in grep 2.14"
