Fini Jastrow ef1f35368e patch-em-all: Display error messages if patching fails ... [why] All error stream outputs of `font-patcher` are suppressed, because they are very noisy and usually are ignored. But when the patching fails for some reason we do not know why. Especially if that happens during CI runs. [how] Instead of dropping the stderr we store it in an envvar; and output it to stdout if patching failed. `printf` is needed because `echo` is lousy with multiple lines.
