parser: fill invalid infix and suffix actions by None This can simplify the expansion of (prefix, infix, suffix) actions.

parser: add comment about structure of elements to each table

shelve: omit incorrect 'commit' suggestion at 'hg shelve -i' Before this patch, 'hg shelve -i' under non-interactive mode suggests 'use commit instead', and it obviously incorrect, because what user wants to do isn't 'commit' but 'shelve'. To omit incorrect 'commit' suggestion at 'hg shelve -i', this patch specifies 'None' for 'cmdsuggest' argument of 'cmdutil.dorecord()'.

record: omit meaningless 'qrefresh' suggestion at 'hg qrefresh -i' Before this patch, 'hg qrefresh -i' under non-interactive mode suggests 'use qrefresh instead', and it obviously meaningless. To omit meaningless 'qrefresh' suggestion at 'hg qrefresh -i', this patch specifies 'None' for 'cmdsuggest' argument of 'cmdutil.dorecord()'.

record: omit meaningless 'qnew' suggestion at 'hg qnew -i' Before this patch, 'hg qnew -i' under non-interactive mode suggests 'use qnew instead', and it obviously meaningless. To omit meaningless 'qnew' suggestion at 'hg qnew -i', this patch adds internal function '_qrecord()' and specifies 'cmdsuggest' for each of 'qrecord' and 'qnew' separately.

record: omit meaningless 'commit' suggestion at 'hg commit -i' Before this patch, 'hg commit -i' under non-interactive mode suggests 'use commit instead', and it obviously meaningless. This patch makes 'record.record'()' examine 'ui.interactive()' and show suggestion by itself before calling 'commands.commit()'. This allows 'commands.commit()' to specify 'None' for 'cmdsuggest' argument of 'cmdutil.dorecord()' to omit meaningless 'commit' suggestion at 'hg commit -i'.

cmdutil: allow callers of cmdutil.dorecord to omit suggestion Interactive committing under non-interactive mode shows command suggestion, but sometimes it is meaningless. command suggestion usability ------------ ---------- ----------- record commit commit -i commit meaningless qrecord qnew qnew -i qnew meaningless qrefersh -i qrefresh meaningless shelve -i commit incorrect ------------ ---------- ----------- This patch allows callers of 'cmdutil.dorecord()' to omit meaningless suggestion by passing None or so for 'cmdsuggest' argument of it. This is a preparation for subsequent patches, which fix each suggestion issues above.
