templatefuncs: do not stringify result of if*() expression
Returning a generator means that the result is a byte string. I can't find
any reason to make the "if" condition lazy since it is evaluated anyway
when {if()} has to be evaluated. So let's simply make if*() return an input
expression unmodified.
Test for the heuristic copytracing algorithm
============================================
$ cat >> $TESTTMP/copytrace.sh << '__EOF__'
> initclient() {
> cat >> $1/.hg/hgrc <<EOF
> [experimental]
> copytrace = heuristics
> copytrace.sourcecommitlimit = -1
> EOF
> }
> __EOF__
$ . "$TESTTMP/copytrace.sh"
$ cat >> $HGRCPATH << EOF
> [extensions]
> rebase=
> shelve=
> EOF
NOTE: calling initclient() set copytrace.sourcecommitlimit=-1 as we want to
prevent the full copytrace algorithm to run and test the heuristic algorithm
without complexing the test cases with public and draft commits.

When the sourcecommitlimit is small and we have more drafts, we use heuristics only
$ hg rebase -s 8b6e13696 -d .
rebasing 1:8b6e13696c38 "added more things to a"
other [source] changed a which local [dest] deleted
use (c)hanged version, leave (d)eleted, or leave (u)nresolved? u
unresolved conflicts (see hg resolve, then hg rebase --continue)
[1]
But when we have "sourcecommitlimit > (no. of drafts from base to c1)", we do
fullcopytracing
$ hg rebase --abort
rebase aborted
$ hg rebase -s 8b6e13696 -d . --config experimental.copytrace.sourcecommitlimit=100
rebasing 1:8b6e13696c38 "added more things to a"
