 Test that removing .hgsubstate doesn't break anything:
 
   $ hg rm -f .hgsubstate

   nothing changed

 Test behavior of add for explicit path in subrepo:
   $ cd ..
   $ hg init explicit
   $ cd explicit
   $ echo s = s > .hgsub
   $ hg add .hgsub
   $ hg init s
   $ hg ci -m0
 Adding with an explicit path in a subrepo adds the file
   $ echo c1 > f1
   $ echo c2 > s/f2
   $ hg st -S
   ? f1
   ? s/f2
   $ hg add s/f2
   $ hg st -S
   A s/f2
   ? f1
   $ hg ci -R s -m0
   $ hg ci -Am1
   adding f1
 Adding with an explicit path in a subrepo with -S has the same behavior
   $ echo c3 > f3
   $ echo c4 > s/f4
   $ hg st -S
   ? f3
   ? s/f4
   $ hg add -S s/f4
   $ hg st -S
   A s/f4
   ? f3
   $ hg ci -R s -m1
   $ hg ci -Ama2
   adding f3
 Adding without a path or pattern silently ignores subrepos
   $ echo c5 > f5
   $ echo c6 > s/f6
   $ echo c7 > s/f7
   $ hg st -S
   ? f5
   ? s/f6
   ? s/f7
   $ hg add
   adding f5
   $ hg st -S
   A f5
   ? s/f6
   ? s/f7
   $ hg ci -R s -Am2
   adding f6
   adding f7
   $ hg ci -m3
 Adding without a path or pattern with -S also adds files in subrepos
   $ echo c8 > f8
   $ echo c9 > s/f9
   $ echo c10 > s/f10
   $ hg st -S
   ? f8
   ? s/f10
   ? s/f9
   $ hg add -S
   adding f8
   adding s/f10 (glob)
   adding s/f9 (glob)
   $ hg st -S
   A f8
   A s/f10
   A s/f9
   $ hg ci -R s -m3
   $ hg ci -m4
 Adding with a pattern silently ignores subrepos
   $ echo c11 > fm11
   $ echo c12 > fn12
   $ echo c13 > s/fm13
   $ echo c14 > s/fn14
   $ hg st -S
   ? fm11
   ? fn12
   ? s/fm13
   ? s/fn14
   $ hg add 'glob:**fm*'
   adding fm11
   $ hg st -S
   A fm11
   ? fn12
   ? s/fm13
   ? s/fn14
   $ hg ci -R s -Am4
   adding fm13
   adding fn14
   $ hg ci -Am5
   adding fn12
 Adding with a pattern with -S also adds matches in subrepos
   $ echo c15 > fm15
   $ echo c16 > fn16
   $ echo c17 > s/fm17
   $ echo c18 > s/fn18
   $ hg st -S
   ? fm15
   ? fn16
   ? s/fm17
   ? s/fn18
   $ hg add -S 'glob:**fm*'
   adding fm15
   adding s/fm17 (glob)
   $ hg st -S
   A fm15
   A s/fm17
   ? fn16
   ? s/fn18
   $ hg ci -R s -Am5
   adding fn18
   $ hg ci -Am6
   adding fn16
 
 Test behavior of forget for explicit path in subrepo:
 Forgetting an explicit path in a subrepo untracks the file
   $ echo c19 > s/f19
   $ hg add s/f19
   $ hg st -S
   A s/f19
   $ hg forget s/f19
   $ hg st -S
   ? s/f19
   $ rm s/f19
   $ cd ..
