Yes. The . simply matches one character. If one needs to match "(" one
has to escape it: \( and as there is seemingly the shell involved, the \
itself has also to be escaped. As I always forget whether only the \ or
also the ( needs to be escaped ("\\(" vs. "\\\("), I simply use the dot.
(Answer:  \\( is enough; thus to match "bind(c)" one has to use
"bind\\(c\\)".)

Thanks for the review.
