Previously the regex would match from /bin/ to a closing quote. However, this
is greedy, so will match up until the last ". This causes problems when there
are several quotes on the same line, for example:
org-effectiveness.el:
196: (call-process "/bin/bash" nil t nil "-c" strplot)
Therefore, change . to \S so that it doesn't include whitespace
characters. Changing to a lazy quantifier would be an option, if that were
supported.

expression used.
