Quid uses POSIX.2 modern regex, aka extended regex, the same as egrep or
grep -e. This is slightly different from perl regex.

"man 7 regex"
and
"man egrep".

The exact capabilities depends on the regex library of your OS. Most
regex libraries have extensions beyond the POSIX specifications.

At least braket expressions [...] , grouping (...), repetition ranges x+
x? x{..} and alternatives x|y is supported. Also the special symbols $
and ^, and escaping using the \ character.
