shelve: move commitfunc creation to a separate function
Special commitfuncs are created as closures at least twice in shelve's
code and one time special commitfunc is used within another closure.
They all serve very specific purposes like temporarily tweak some
configuration or enable editor, etc. This is not immediately important
to someone reading shelve code, so I think moving this logic to a separate
function is a good idea.

6 """extend schemes with shortcuts to repository swarms | |
7 | |
8 This extension allows you to specify shortcuts for parent URLs with a | |
9 lot of repositories to act like a scheme, for example:: | |
10 | |
11 [schemes] | |
12 py = http://code.python.org/hg/ | |
13 | |
14 After that you can use it like:: | |
15 | |
16 hg clone py://trunk/ | |
17 | |
18 Additionally there is support for some more complex schemas, for | |
19 example used by Google Code:: | |
20 | |
21 [schemes] | |
22 gcode = http://{1}.googlecode.com/hg/ | |
23 | |
24 The syntax is taken from Mercurial templates, and you have unlimited | |
25 number of variables, starting with ``{1}`` and continuing with | |
26 ``{2}``, ``{3}`` and so on. This variables will receive parts of URL | |
27 supplied, split by ``/``. Anything not specified as ``{part}`` will be | |
28 just appended to an URL. | |
29 | |
30 For convenience, the extension adds these schemes by default:: | |
31 | |
32 [schemes] | |
33 py = http://hg.python.org/ | |
34 bb = https://bitbucket.org/ | |
35 bb+ssh = ssh://hg@bitbucket.org/ | |
36 gcode = https://{1}.googlecode.com/hg/ | |
