After finding out that:
 (1) It looks like the syntax is defined by the first atom in pairs
     `\<' and `\|', `\cr' and `\rc', and `\cresc' and `\endcresc'
     -- this was found by mixing the definitions.
and
 (2) The sorter syntaces `\cr' and `\<' seem to produce similar results,
     which is the angle-syntax.
 (3) The longer syntax `\cresc' `\endcresc' produces text 'cresc - - -'.
Ok, now your point becomes more clear.

The definition for `\cresc' and `\endcresc, for example, are in
`ly/spanners-init.ly':

cresc = \notes {
  #(ly:export (make-event-chord (list cr)))
  \property Voice.crescendoText = \markup { \italic "cresc." }
  \property Voice.crescendoSpanner = #'dashed-line
}

endcresc = \notes {
  #(ly:export (make-event-chord (list rc)))
  \property Voice.crescendoText \unset
  \property Voice.crescendoSpanner \unset
}

Therefore, \cresc is nothing but \cr with crescendoText and
crescendoSpanner set to some values. The logic is clear and sharp.
Similarly, you can define `\moltocresc' and `\endmoltocresc' to meet
your needs.
