more importantly, patch(1) has an option --ignore-whitespace<br>
that helps applying patches to a revised Cabal file which<br>
suddenly comes along with CRLF line endings. Using that flag<br>
with diff(1) when creating the patch is a good idea, but it<br>
won't make the patch resistant against failures when it's<br>
applied to a modified Cabal file.<br>

<br>
This option is actually somewhat dangerous when applied in<br>
cases where the underlying source relies on layout to convey<br>
structure, because changes in indention will be lost with<br>
that flag enabled.<br>
<br>
Generally speaking, Hackage's policy of adding CRLFs to<br>
edited files seems like a bad idea. The least intrusive<br>
choice would be to follow whatever line-ending convention<br>
the original Cabal file has and to adhere to that.<br>
<br>
Anyway, I'll throw in a historical footnote for good<br>
measure: [1]<br>
