(It's *no* trailing period that's standard. gfortran has a mixture, but
pretty consistently uses initial uppercase.)
The rule that the sentence is considered to start with the program or file
name at the start of the line, so that the diagnostic starts with a
lowercase letter (and that diagnostics are formatted with file names and
line and column numbers in a particular format) is actually from the GNU
Coding Standards; GCC has extended it to include the "error:", "warning:"
etc. notation before the message text. Likewise, the rule against
trailing period is also from the GCS.
If gfortran wishes to move towards the GCS-specified formatting it would
be nice to work out how to add support for features gfortran's diagnostics
code has that the generic code doesn't (in particular caret diagnostics)
to the generic code so that gfortran can move to sharing the generic code
rather than needing its own implementation. (Sharing the generic code
would in turn allow gfortran to benefit from generic features such as
-Werror=option-name.)
