man page in r-minimal contains timestamp |

The compressed man page at “share/man/man1/R.1.gz” provided by r-minimal
contains a time-dependent string.
Comparing the uncompressed man pages built at different times on
different machines shows me this:
--8<---------------cut here---------------start------------->8---
diff /tmp/berlin/share/man/man1/R.1 /tmp/hydra/share/man/man1/R.1
2c2
< .TH R "1" "July 2017" "R 3.4.0" FSF
---
> .TH R "1" "May 2017" "R 3.4.0" FSF
--8<---------------cut here---------------end--------------->8---
The man page is created with a rule in “doc/Makefile.in”:
@$(HELP2MAN) --include=$(srcdir)/R.aux --no-info --output=R.1 \
--name="a language for data analysis and graphics" \
$(top_builddir)/bin/R
“doc/R.aux” does not contain a timestamp, nor does the help output of R
itself. Is help2man to blame here?

This is now fixed with commit 174fbd5f3b2f286cf06e58787853db6b8f0f5b35.
