The problem manifests on platforms where '$' does not match new line. According to: http://cplusplus.github.io/LWG/lwg-active.html#2343 some RegEx implementations e.g. GCC have multiline property turned off so '$' does not match a new line character and the Option parser fails to recognise an option's parameter if it is present. Example ======= Usage: my_app [--so-long-option-that-the-description-is-on-a-new-line <param>] Options: --so-long-option-that-the-description-is-on-a-new-line <param> Something very important [default: 43] modified: docopt.cpp

Sorry for the delay ... I've been trying to get some of these taken care of, and would be willing to merge this. However, it looks like other pull requests have now created a merge conflict. Do you mind rebasing this and leaving a comment? Then we can have travis verify that things still look ok. |

I just need a rebase of it to resolve the merge conflict. |

Is this PR a duplicate of PR #55? |

Hi,
thanks for the good work on docopt.cpp.
I've submitted few pull requests to address some problems I've found while using docopt.cpp in our application.
This is again a simillar problem to pull request #23. Perhaps I should have squashed them together...

All test are passing on gcc 5.1 and msvc2015.
