changegroupsubset: use readdelta() fast path when delta is against a parent

run-tests: handle .tst not ending with an LF

minirst: small code cleanup

cat: fix cat without -r, broken by 0ae35296fbf4 The default revision for revsingle() is now '.' instead of None. This preserves the behavior of cat prior to it using revsingle().

revsets: introduce revsingle helper revsingle returns a context for the last revision of the supplied revspec

revsets: make revpair revsets-aware revpair returns the first and last members of the computed revset(s)

revset: lower precedence of minus infix (issue2361)

revset: fix #branch in urls for outgoing() hg log -r 'outgoing(..)' ignored #branch in some cases. This patch fixes it. The cases where it misbehaved are now covered by the added test-revset-outgoing.t

heads: mention STARTREV in synopsis and help for --rev Before this change, "hg help heads" said hg heads [-ac] [-r REV] [REV]... [...] If STARTREV is specified, only those heads that are descendants of STARTREV will be displayed. [...] -r --rev REV show only heads which are descendants of REV [...] which made little sense since there are two things called REV in the synopsis and nothing called STARTREV. A little digging reveals that the "[-r REV]" part of the synopsis was introduced in 8e503fa54d2d, changed to "[-r STARTREV]" in 2bcef677a6c3, and then changed back to "[-r REV]" in 4b02fc71bbba. The last change seems to be based on a patch[1] on our mailinglist that actually *inserted* STARTREV again in the help for the command line option itself. For some reason, the patch was changed to remove STARTREV from the synopsis. This change finally makes the help consistent by putting STARTREV back into the help in all places where it is needed: hg heads [-ac] [-r STARTREV] [REV]... [...] If STARTREV is specified, only those heads that are descendants of STARTREV will be displayed. [...] -r --rev STARTREV show only heads which are descendants of STARTREV [...] This was not possible until 40c06bbf58be, which introduced the possibility of naming the meta variables for each option.
