In the immortal words of @paulp:
 "Can we please, please not do this:

  import PatternMatchingStats._
  import global.{phase, currentRun, Symbol,
    Apply, Bind, CaseDef, ClassInfoType, Ident, Literal, Match,
    Alternative, Constant, EmptyTree, Select, Star, This, Throw, Typed, UnApply, (...)"

Let's simplify merges, by making our imports mono-line !

Thanksfully, in the IDE, we don't do (many) *mutli-line* braced Imports, so it
was enough to filter them with the following one-liner:

for i in `find ./ -type f -name "*.scala"`; do perl -nle 'if (m/^(\s*)import\s([^\n]+?){([^}]*?)}$/smg){my ($s,$x,@y)=($1,$2,split /,\s*(?!_|\s)/,$3); foreach $dep (@y){$dep =~ s/^\s+|\s+$//g; $dep=($dep =~ m/=>/)?"{ $dep }":$dep;print "${s}import $x$dep";}} else {print $_;}' $i > $i.nu; mv $i.nu $i; done

Note the negative lookahead to avoind busting final wildcards in
braced imports (see the Spec version 2.9, section 4.7), .

If you want to do this on a repo that contains multi-line braced
imports, look into unsetting the special variable '$/' of perl, and
relax the condition on the presence of new lines in the second capture
group of the regex above. I strongly advise against doing this
automatically on such a repo, though.

Fixes of multiline braced imports (manual).

Let this be the end of this lazy, messy, mergepain-inducing practice.
