Fix CI failure on maybe-uninitialized compiler warning - #205

Conversation
Some GCC versions say:
ttyplot.c:359:16: error:
‘y2_start’ may be used uninitialized [-Werror=maybe-uninitialized]
and a similar warning (promoted to error) for y2_end. These are false
positives: the variables are initialized if they ever get used. It is,
however, easy to restructure the code in order to get the initialization
and usage of the variables under the same ‘if’ test, so let's silence
the warning this way.
Fixes: https://github.com/tenox7/ttyplot/actions/runs/17030161145/job/48271411839
This option is not needed anymore. Furthermore, it is not supported by clang. This reverts commits 8d8d752 ("fix gh actions") and 714f210 ("fix retarded flags"). Fixes: https://github.com/tenox7/ttyplot/actions/runs/17030161145/job/48271411825

Some GCC versions warn:
These are false positives. However, in combination with the
-Werrorcompiler option, they cause a CI failure on GCC 14 / Ubuntu.Commits 8d8d752 and 714f210 attempted to fix the failure by providing the
-Wno-error=maybe-uninitializedcompiler option. However, they did not fix the failure on Ubuntu, and they caused another failure on clang 18 on macOS:This pull request solves the issue in a different way: by moving the initialization of
y2_startandy2_endcloser to where they are used (within the sameifstatement), the warning goes away. Then, the compiler option-Wno-error=maybe-uninitializedis not needed anymore.
