Shivaram Lingamneni 6e9a31a574 use confusables.SkeletonTweaked to fix the test 2019-06-19 05:24:09 -04:00
Shivaram Lingamneni be4d098945 fix an edge case in skeletonization 
'm' skeletonizes to 'rn' (but is exempted by the isBoring check),
but the fullwidth 'ｍ' does not skeletonize to anything. The root cause
of this is the (still unexplained) patchiness of the skeleton mapping
for fullwidth -> standard-width Latin characters; the fix is to perform
width mapping first, before either skeletonization or isBoring.

Euan Kemp 449ef4cea1 strings: disallow ':' in nicks 
This matches the behavior of inspircd at the very least.

Previously, the comment above that section claimed ':' should be
disallowed, but the code didn't do so.

I also simplified the code a little bit and added tests.

Robin Burchell 6ad97f7e5d irc: Switch to golang.org versions, not google code versions of dependencies. 
This has a few advantages:
* the google code versions are no longer maintained
* the google code versions are using mercurial (which I don't have installed)
