Supports multiple renames

[babarot]

Make the rename-to tag support to multiple renames. Here is an example:

foo/bar
├── README.md
└── bin
    ├── a.sh
    ├── b.sh
    └── c.sh

If you want to load as a command all files ending in sh within the bin directory of that repository:

zplug "foo/bar", as:command, use:"bin/*.sh", rename-to:"*"

$ ls -l ~/.zplug/bin
lrwxr-xr-x 1 b4b4r07 staff  50 Dec 18 01:03 a -> /Users/b4b4r07/.zplug/repos/foo/bar/bin/a.sh
lrwxr-xr-x 1 b4b4r07 staff  54 Dec 18 01:03 b -> /Users/b4b4r07/.zplug/repos/foo/bar/bin/b.sh
lrwxr-xr-x 1 b4b4r07 staff  65 Dec 18 01:03 c -> /Users/b4b4r07/.zplug/repos/foo/bar/bin/c.sh

The above zplug syntax means this in zmv command.

zplug "foo/bar", as:command, use:"bin/(*).sh", rename-to:'$1' # single quotes

It is more convenient to use shorthand notation when executing from the command line. However, in the case of zplug, since it is assumed to write in zshrc file, the latter syntax will be easier to understand than the former notation.

Like zmv command with no options specified, you can now rename a command to load with the string captured with use tag.

zplug 'foo/bar', as:command, use:'(*).sh', rename-to:'$1'

Also,

zplug 'reorx/httpstat', as:command, use:'(httpstat).py', rename-to:'$1'

is acceptable.

Therefore, expand the glob and the capture results even if no wildcards specified.
