Support relative path for `--bin` flag

[jamesottaway]

I want to add this line in my .freshrc:

fresh sivel/speedtest-cli speedtest_cli.py --bin=speedtest

and have it symlink ~/.fresh/source/sivel/speedtest-cli/speedtest_cli.py to ~/bin/speedtest.

The --bin flag currently only accepts values starting with ~ or / and hence can assume you are giving it the full path to symlink to.

Ideally it would allow --bin=foo and symlink into the default bin path (currently ~/bin) with the custom name, in this case foo.

This behaviour should probably also be extended to --file for consistency. e.g. --file=foo should behave the same as --file=~/.foo.

How would that affect the 'Building files without symlinking' example in README.md, where this line:

fresh zsh-users/zsh-syntax-highlighting zsh-syntax-highlighting.zsh --file=vendor/zsh-syntax-highlighting.zsh

would currently symlink zsh-users/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh to ~/.zsh-syntax-highlighting.zsh?

Should the new style only work if the value appended to --file= is a filename, not a relative path?

[jasoncodes]

--file=vendor/zsh-syntax-highlighting.zsh will not perform any symlinking. The new behaviour would only trigger if the value is present and does not contain any slashes.

Cool, I thought that's what you were hinting at, just wanted to be sure.
