Add -e option: Interrupt via Ctrl+C, Proper Makefile, and Cleanup sl.h

[ryanmjacobs]

Add -e option to allow interrupt via Ctrl+C. So users can, alias sl='sl -e' if they don't want to wait each time for sl to finish running.

• Makefile now includes: install, uninstall, and clean. Therefore, users can install sl by running:

make
make install

• Add header guards to sl.h, and move function prototypes to sl.h.
• README.ja.md and sl.1.ja still need to be updated (I don't know Japanese).

Sorry for replying late.
The -e option is a local extension for the debian package.
I'm still wondering that users really need the option.

[ryanmjacobs]

That's fine if you don't merge it.
I just created this fork because I wanted the -e option on my system.
If other users want it too, they can grab it from my fork.

I get impatient because I mistype ls as sl very often 😛

Hm. I applied this patch and the manpage has changed and the source does say it's changed but -e doesn't work...

[ryanmjacobs]

@Jonathan50 Sorry for the late reply. My inbox has been stuffed lately.

Can you please try these commands in order?

$  git clone https://github.com/ryanmjacobs/sl
$ cd sl
$ make
$ ./sl -e

[jeandrek]

It works. But if I modify the PKGBUILD to apply the patch it doesn't work.

[ryanmjacobs]

Can you try this PKGBUILD?

(I basically took sl-git, and switched out mtoyoda with ryanmjacobs)

[jeandrek]

It works great thanks
