Subject: i3bar: replace magic numbers with more meaningful constructs
X-Git-Tag: 4.15~38^2
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=222d8210abaae69f91f8834a6d3045489d5b48ef;p=i3%2Fi3

i3bar: replace magic numbers with more meaningful constructs

In i3bar/src/config.c we compare string lengths agains magic numbers.
This change replaces those numbers with the lengths of the strings they
represent.
