If this variable is non-@code{nil}, a period followed by just one space
does not count as the end of a sentence, and the filling functions
avoid breaking the line at such a place.
@item line-spacing
@kindex line-spacing @r{(text property)}
-A newline can have a @code{line-spacing} text or overlay property
-that controls the height of the corresponding display line.
-@c ??? Which display line is "corresponding"?
-The @code{line-spacing} property overrides the default frame line
-spacing and the buffer local @code{line-spacing} variable. We will
-call the property value @var{line-spacing}.
+A newline can have a @code{line-spacing} text or overlay property that
+controls the height of the display line ending with that newline. The
+property value overrides the default frame line spacing and the buffer
+local @code{line-spacing} variable. We will call the property value
+@var{line-spacing}.
If @var{line-spacing} is a positive integer, the value specifies
additional vertical space, below the display line, in pixels.
@item line-height
@kindex line-height @r{(text property)}
A newline can have a @code{line-height} text or overlay property that
-controls the total height of the corresponding display line.
-@c ??? Which display line is "corresponding"?
+controls the total height of the display line ending in that newline.
We will call the property value @var{line-height}.
-If @var{line-height} is 0, the newline does not contribute to the
-height of the display row; instead the height of the newline glyph is
-reduced.
-@c ??? That is not clear. Reduced how much?
-In that case, any @code{line-spacing} property on
-this newline is ignored. This can be used to tile small images or
-image slices without adding blank areas between the images.
-@c ??? Precisely which of these features does ``this'' mean?
+If @var{line-height} is 0, the height of the line is determined solely
+from its contents; nothing is added. Any @code{line-spacing} property
+on this newline is ignored. This case is useful for tiling small
+images or image slices without adding blank areas between the images.
If @var{line-height} is a positive integer, the value specifies the
minimum line height in pixels. The line's ascent height is
This function applies a translation table to the characters in the
buffer between positions @var{start} and @var{end}.
-The translation table @var{table} is a string; @code{(aref @var{table}
-@var{ochar})} gives the translated character corresponding to
-@var{ochar}. If the length of @var{table} is less than 256, any
+The translation table @var{table} is a string or a char-table;
+@code{(aref @var{table} @var{ochar})} gives the translated character
+corresponding to @var{ochar}. If @var{table} is a string, any
characters with codes larger than the length of @var{table} are not
altered by the translation.
