Actually, it depends on the regex interpreter. As I recall, in PERL, you
use (...) to represent a group of characters that need to be remembered
for later recalling. Under sed, \(...\) is used to do the same. (Perl
also uses $1 instead of \1 for recalling, doesn't it?)
If you don't put the backslashes in front of ( or ), you match the
parenthesis characters, I think. The same *seems* to be true for curly
braces... on Sed, anyway.
