* misc: consolidate macro style USAGE_HELP_OPTIONSRuediger Meier2017-06-291-2/+2
| | | | | | | | | changed in include/c.h and applied via sed: sed -i 's/fprintf.*\(USAGE_MAN_TAIL.*\)/printf(\1/' $(git ls-files -- "*.c") sed -i 's/print_usage_help_options\(.*\);/printf(USAGE_HELP_OPTIONS\1);/' $(git ls-files -- "*.c") Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>
* misc: introduce print_usage_help_options()Ruediger Meier2017-06-271-2/+1Star
| | | | | | | | | | | | Consolidate --help and --version descriptions. We are now able to align them to the other options. We changed include/c.h. The rest of this patch was generated by sed, plus manually setting the right alignment numbers. We do not change anything but white spaces in the --help output. Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>
* misc: cosmetics, remove argument from usage(FILE*)Ruediger Meier2017-06-261-3/+4
| | | | | | | | | | | | | | This patch is trivial and changes nothing, because we were always using usage(stdout) Now all our usage() functions look very similar. If wanted we could auto-generate another big cosmetical patch to remove all the useless "FILE *out" constants and use printf and puts rather than their f* friends. Such patch could be automatically synchronized with the translation project (newlines!) to not make the translators sick. Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>

| | | | | | | | | | | | | | | | This change fixes all shadow declarations. The worth while to mention fix is with libfdisk sun geometry.
