cleanup: update references to /help/ that should now be /helptext/

I noticed this only because the WiX build was broken after
2e017696181f. I haven't tested this change with WiX, but it seems
pretty obvious by inspection this should fix it.

Test variable expansion
-----------------------

Subrepository paths shouldn't be expanded, but we fail to handle them
properly. Any local repository paths are expanded.

on commit:

  $ mkdir envvar
  $ cd envvar
  $ hg init main
  $ cd main
  $ hg init sub1
  $ cat <<'EOF' > sub1/hgrc
  > [hooks]
  > log = echo pwned

  $ hg -R sub1 ci -qAm 'add sub1 files'
  $ hg -R sub1 log -r. -T '{node}\n'
  39eb4b4d3e096527668784893a9280578a8f38b8
  $ echo '$SUB = sub1' >> .hgsub
  $ SUB=sub1 hg ci -qAm 'add subrepo "$SUB"'
  abort: subrepo path contains illegal component: $SUB
  [255]

  $ cd ..

on clone (and update) with various substitutions:

  $ hg clone -q main main2
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main2

  $ SUB=sub1 hg clone -q main main3
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main3

  $ SUB=sub2 hg clone -q main main4
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main4

on clone empty subrepo into .hg, then pull (and update), which at least fails:

  $ SUB=.hg hg clone -qr0 main main5
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main5

  [255]
  $ cat main5/.hg/hgrc | grep pwned

  $ SUB=.hg hg clone -q main main6
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main6
  $ cat main6/.hg/hgrc | grep pwned

  $ SUB=.hg/foo hg clone -q main main7
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main7
  $ test -d main7/.hg/.hg

on clone (and update) into outer tree:

  $ SUB=../out-of-tree-write hg clone -q main main8
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main8

on clone (and update) into e.g. $HOME, which doesn't work since subrepo paths
are concatenated prior to variable expansion:

  $ SUB="$TESTTMP/envvar/fakehome" hg clone -q main main9
  abort: subrepo path contains illegal component: $SUB
  [255]
  $ ls main9 | wc -l
  \s*0 (re)

  $ ls

  main2
  main3
  main4
  main5
  main6
  main7
  main8
  main9
  $ cd ..

Test tilde
----------

The leading tilde may be expanded to $HOME, but it can be a valid subrepo
path in theory. However, we want to prohibit it as there might be unsafe
handling of such paths.

on commit:

  $ hg init tilde
  $ cd tilde
  $ hg init './~'
  $ echo '~ = ~' >> .hgsub
  $ hg ci -qAm 'add subrepo "~"'
  abort: subrepo path contains illegal component: ~
