[bug#70169,v3,10/13] maint: Avoid EPS generation to fail silently, ensure reproducibility.
Commit Message
Currently, Graphviz' dot does not insert a %%CreationDate. ImageMagick's
convert on PNG->EPS does insert a %%CreationDate but it respects
SOURCE_DATE_EPOCH.
* doc/local.mk (.png.eps): Split single shell command into separate recipe
lines, prefixed by $(AM_V_at).
(.dot.png): Likewise. Check that generated EPS file has no %%CreationDate.
