trim re to get >0 matches from str_match_all

[dhicks]

str_match_all was returning 0 matches. The problem seems to be the final \\} in the regular expression re; after removing these characters everything worked as expected (including Synctex and command-clicking in TeXShop).

Thanks for reporting and investigating the problem you encountered! There might indeed be an issue with the regex as there is no or i could not find any definition of a concordance file and just inferred. Its structure from examples. Could you post the concordance file in question? Just removing the closing bracket from the expression might hide an underlying problem and leave parts of the concordance file unparsed.
Please send further pull requests to https://github.com/EmmanuelCharpentier/patchKnitrSynctex where active development takes place.

Thanks for the pointer to the other repo. Taking a closer look, it looks like the underlying problem is that my concordance file has three lines; see below. The current regex and my pull request yesterday both assume there are exactly two lines. I can get the regex to match the entire concordance file, but then there are newlines and a % that cause errors with rleValues. I'm out of time today, but I'll come back to this, and submit the pull request to the other repo.
