[bug #18633] regular expressions case-insensitivity

[Benno Schulenberg]

Follow-up Comment #1, bug #18633 (project grep):

Sounds like a locale problem.  If you type:
  grep '^[a-E]' filename
do all ten letters get included?
And what happens when using:
  LC_ALL=C grep '^[A-Ea-e]' filename

What is the output of 'locale' and of 'type -a grep'?


(In CVS there's another problem, "grep -i --color '^[A-E]'" does
not colour the matches, whereas "grep -i --color '^[a-e]'" does.)
