bug#18950: [PATCH] 24.4.51; Wrong type argument: stringp on completing an asterisk in eshell with pcomplete-cycle-completions disabled

[samer <samer@samertm.com>]

Hi,

The function pcomplete-parse-arguments wasn't completing the input when
pcomplete-cycle-completions was nil, and so pcomplete would pass control
to one of eshell's completion functions, which would blow up when given
a list by pcomplete-arg (which is strange, because it's valid for
pcomplete-arg to return a list). But there is no reason for
pcomplete-parse-arguments to care about whether the user wants to cycle
completions, as only really matters in pcomplete-stub. The following
patch fixes the bug by making pcomplete-parse-arguments not care about
the value of pcomplete-cycle-completions.

Best,
Samer
