Typing M-q in second paragraph should produce:

@raxod50, does this issue still exist in a recent git snapshot?

If so, I imagine message-mode (or another email composing mode) could be consulted for a solution.

[raxod502]

Yes, the problem still exists.

@raxod502, thank you for confirming :-) @syohex, does this look like a blocker for v2.4 to you, or should a fix be deferred to a later release? See notes in previous messages for possible hints for a fix.

[syohex]

I have merged #477. Please check latest version.

[raxod502]

Nice!

Thank you :-)
