Details:

When there are multiple lines in a text() command, Matlab uses the same
vertical spacing for every line.  Octave seems to inspect each line and use a
different vertical spacing based on the characters present (characters with
descenders or CAPITAL letters will have different heights).

Sample code is attached


## '[]' should create a newline with same height as regular line
clf;
text (.3, .8, {"Hello", 'world', [], 123}, 'fontsize', 20)
text (.5, .8, {"Hello", 'world', 1, 123}, 'fontsize', 20)


The resulting plot is attached as well.
