Thanks, pushed to master.

In the future, please provide a commit log message that is according
to our coding standards:

 . mention the names of functions in which you make changes
 . start sentences with a capital letter
 . mention the bug number

Here's the log message I used in this case:

	* src/xdisp.c (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
	Use pD directives for ptrdiff_t values instead of pI, to avoid
	compilation warnings on 64-bit hosts.  (Bug#27597)
