git-effort: replace "wc | cut" with "wc | awk"

[ihoro]

It looks "cut" may have different behaviour, e.g. BSD one works the way
git-effort doesn't expect. "awk" looks to be one of possible fixes here.

[ihoro]

A little example to give an idea:

$ wc -l bin/git-effort
     145 bin/git-effort
$ wc -l bin/git-effort | cut -d' ' -f1

$ wc -l bin/git-effort | cut -d' ' -f6
145
$ wc -l bin/git-effort | awk '{print $1}'
145

[ihoro]

I've checked the same with GNU coreutils:

$ wc -l bin/git-effort
145 bin/git-effort
$ wc -l bin/git-effort | cut -d' ' -f1
145
$ wc -l bin/git-effort | awk '{print $1}'
145

So, "wc" looks to be "the one", i.e. behavior diff between GNU & BSD ones.

Finally, awk helps ?

[chernjie]

Perhaps we could consider using stdin, it produce consistent result across GNU and BSD, and it does not depend on cut or awk

$ wc -l < bin/git-effort
145

@chernjie: unfortunately, it still prefixes it with a tab:

$ wc -l < bin/git-effort
     145

@hemanth: yes, "awk" still helps.

[hemanth]

Let's merge this rather than fixing wc?

[ihoro]

@hemanth: yep, there's nothing to do with "wc" itself, it differs from system to system.

Thanks @phigoro 👍
