evolve: make split respect rev args passed without --rev or -r

Currently, if one runs `hg split .` or `hg split`, it will fail
with an exception. This happens becuase we only expect revision
args to be passed as --rev/-r ones and don't treat unnamed args
properly or add default values if no args are provided.

Changing evolution level to createmarkers
  $ echo "[experimental]" >> $HGRCPATH
  $ echo "evolution=createmarkers" >> $HGRCPATH

Running split without any revision operates on the parent of the working copy
  $ hg split << EOF
  > q
  > EOF
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  adding _d
  diff --git a/_d b/_d
  new file mode 100644
  examine changes to '_d'? [Ynesfdaq?] q
  
  abort: user quit
  [255]

Running split with tip revision, specified as unnamed argument
  $ hg split . << EOF
  > q
  > EOF
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  adding _d
  diff --git a/_d b/_d
  new file mode 100644
  examine changes to '_d'? [Ynesfdaq?] q
  
  abort: user quit
  [255]

Running split with both unnamed and named revision arguments shows an error msg
  $ hg split . --rev .^ << EOF
  > q
  > EOF
  abort: more than one revset is given
  (use either `hg split <rs>` or `hg split --rev <rs>`, not both)
