tcsh: Fix autocompletion for no single-hyphen args

[simaoafonso-pwt]

If the parser has no single-hyphen options, the tcsh template would generate a syntax error.

Include a hack to that the autocompletion for the double-hyphen selection does not add an extra space at the end.

Another fix to the tcsh template support, see #56 #57 #58

This seems to break things a little (at least on bash).

That's weird, I only changed the csh function, and this commit to avoid test failures.

I should rebase and retest this.

[simaoafonso-pwt]

Rebased and re-tested, including that test you mentioned, works for me.

Sounds like the test failure is not my fault, pydoc-markdown cannot run correctly on PyPy?

[casperdcl]

Thanks! Rebased now over #139 (should merge that first). Better now?

[simaoafonso-pwt]

LGTM, you can merge this.
