alias: don't shadow commands that we only partially matched (issue2993) (BC)

Previously, if you set an alias for "ci", it'd also shadow "commit"
even though you didn't specify that. This occurred for all commands
with explicit short variations.

Rebasing
D onto H - simple rebase:

  $ hg clone -q -u . a a1
  $ cd a1

  $ hg tglog
  @  7: 'H'
  |
  | o  6: 'G'
  |/|
  o |  5: 'F'
  | |
  | o  4: 'E'
  |/
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  

  $ hg rebase -s 3 -d 7
  saved backup bundle to $TESTTMP/a1/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @    7: 'D'
  |\
  | o  6: 'H'
  | |
  | | o  5: 'G'
  | |/|
  | o |  4: 'F'
  | | |
  | | o  3: 'E'
  | |/
  o |  2: 'C'
  | |
  o |  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


D onto F - intermediate point:

  $ hg clone -q -u . a a2
  $ cd a2

  $ hg rebase -s 3 -d 5
  saved backup bundle to $TESTTMP/a2/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @    7: 'D'
  |\
  | | o  6: 'H'
  | |/
  | | o  5: 'G'
  | |/|
  | o |  4: 'F'
  | | |
  | | o  3: 'E'
  | |/
  o |  2: 'C'
  | |
  o |  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


E onto H - skip of G:

  $ hg clone -q -u . a a3
  $ cd a3

  $ hg rebase -s 4 -d 7
  saved backup bundle to $TESTTMP/a3/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  6: 'E'
  |
  o  5: 'H'
  |
  o  4: 'F'
  |
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


F onto E - rebase of a branching point (skip G):

  $ hg clone -q -u . a a4
  $ cd a4

  $ hg rebase -s 5 -d 4
  saved backup bundle to $TESTTMP/a4/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  6: 'H'
  |
  o  5: 'F'
  |
  o  4: 'E'
  |
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


G onto H - merged revision having a parent in ancestors of target:

  $ hg clone -q -u . a a5
  $ cd a5

  $ hg rebase -s 6 -d 7
  saved backup bundle to $TESTTMP/a5/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @    7: 'G'
  |\
  | o  6: 'H'
  | |
  | o  5: 'F'
  | |
  o |  4: 'E'
  |/
  | o  3: 'D'
  | |
  | o  2: 'C'
  | |
  | o  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


F onto B - G maintains E as parent:

  $ hg clone -q -u . a a6
  $ cd a6

  $ hg rebase -s 5 -d 1
  saved backup bundle to $TESTTMP/a6/.hg/strip-backup/*-backup.hg (glob)

  $ hg tglog
  @  7: 'H'
  |
  | o  6: 'G'
  |/|
  o |  5: 'F'
  | |
  | o  4: 'E'
  | |
  | | o  3: 'D'
  | | |
  +---o  2: 'C'
  | |
  o |  1: 'B'
  |/
  o  0: 'A'
  
  $ cd ..


These will fail (using --source):

G onto F - rebase onto an ancestor:

  $ hg clone -q -u . a a7
  $ cd a7

  $ hg rebase -s 6 -d 5
  abort: source is a child of destination
  [255]

F onto G - rebase onto a descendant:

  $ hg rebase -s 5 -d 6
  abort: source is ancestor of destination
  [255]

G onto B - merge revision with both parents not in ancestors of target:

  $ hg rebase -s 6 -d 1
  abort: cannot use revision 6 as base, result would have 3 parents
  [255]


These will abort gracefully (using --base):

G onto G - rebase onto same changeset:

  $ hg rebase -b 6 -d 6
  nothing to rebase
  [1]

G onto F - rebase onto an ancestor:

  $ hg rebase -b 6 -d 5
  nothing to rebase
  [1]

F onto G - rebase onto a descendant:

  $ hg rebase -b 5 -d 6
  nothing to rebase
  [1]

C onto A - rebase onto an ancestor:

  $ hg rebase -d 0 -s 2
  saved backup bundle to $TESTTMP/a7/.hg/strip-backup/5fddd98957c8-backup.hg
