change-log-goto-source is a great function for finding the definition of
a function mentioned in a changelog. I'm looking for some help though
getting it to work recognising tags in the language R (a popular
statistics environment). In R, function names are often include the
period character, e.g. t.test(). When using change-log-goto-source on
these kinds of tags, the correct tag is not found because . is of the
syntax class 'punctuation', and it looks to me like the tags must be made
of elements of syntax class 'word'.
This is also a problem in lisp, as it seems . can be used within lisp
defuns (but not used in practice I think):
(defun test1 (x)
"Test version 1."
t)
(defun test.2 (x)
"Test version 2."
nil)
(defun test3 (x)
"Test version 3."
t)
with the corresponding Changelog

* simple.el (test1): New function.
(test.2): new function.
(test3): new function.
C-c C-c works when point is on test1 and test3, but not test2.
How to fix this? I tried changing the regexp, but this didn't work:
(defconst change-log-tag-re
"(\\(\\(?:\\sw\\|\\s_\\|\\.\\)+\\(?:[, \t]+\\(?:\\sw\\|\\s_\\|\\.\\)+\\)*\\))"
"Regexp matching a tag name in change log entries.")
Apart from lisp and R, I'm not sure which other languages use . in
function names.
best wishes, Stephen
