#
# In jobs mode, the shell commands for creating a target are written to a
# temporary file first, which is then run by the shell. In chains of
# dependencies, these files would end up empty. Since job.c 1.399 from
# 2021-01-29, these empty files are no longer created.
#
# After 2021-01-29, before job.c 1.435 2021-06-16, targets that could not be
# made led to longer error messages than necessary.
