[PATCH] Quote components before using it is pattern

["Jörg Sommer" <joerg@alea.gnuu.de>]

A component might contain a character active in patterns, like * or ().
Take for example the path /tmp/foobar). Passing this and /tmp/foo123 as a
completion to _multi_parts results in an error:

_multi_parts:147: bad pattern: (foo123|foobar))*

The characters in the temporary variable tmp1 must be quote, before the
pattern is build with them.
