We have it everywhere else. Should we change this in general?
If so, that would probably make sense as a followup patch.

Reordered, to make it more sensible.
Excess spaces between @var{DIM} and @tab?
Removed.
Excess third space at the start of the sentence: dot-space-space
Removed.
Unless there are other comments, I'll commit in a couple of days.

+row of the array in the @var{DIM} direction. If @var{MASK} is

+@var{VALUE}, the location returned is that of the first such element
+in array element order if the @var{BACK} is not present or if it is
+@code{.FALSE.}. If @var{BACK} is true, the location returned is that
+of the last such element. If the array has zero size, or all of the
+elements of @var{MASK} are @code{.FALSE.}, then the result is an array
+of zeroes. Similarly, if @var{DIM} is supplied and all of the
+elements of @var{MASK} along a given row are zero, the result value
