Hello,
I have been surprised by the following (I made what I consider a mistake
in a RE with sed(1) but it went unnoticed under NetBSD since it
succeeded when, I think, it should not):
$ echo '$(VAR)' | sed 's/^$(\([^)][^)]*\))$/\1/'
VAR
The problem? the leading '$' is not escaped (I was trying to get the var
name from a Makefile)...
Is this a bug or is this behavior undefined or even required by
POSIX?
Best,
