Thanks, this looks handy!

• There's some package-lint feedback you've missed here.
• I suggest you use the standard more verbose header boilerplate which makes the licence explicit.
• Where you've hard-coded 80 as the default width, I suggest you use the value of the fill-column variable, which users who prefer longer or shorter lines will already have set according to their preferences.

[WJCFerguson]

Good feedback thanks, I'll address those items. The 80 column thing occurred to me after submitting.

[WJCFerguson]

Right, should have resolved those now...

[WJCFerguson]

Oh - I just read your suggestion properly for fill-column - instead I made it another variable. fill-column sounds more sensible... I'll change it to that.
