Details:

While trying to generate the html for a new io package release in
octave-4.1.0+ in Windows 7, the function generate_package_html (from OF
generate-html) gets in an infinite loop (the latter inferred from continuing
CPU usage) with:

generate_package_html ("io", "io-html", "octave-forge")
:
< scrolled out of sight / buffer >
< many, many of: >
GL2PS warning: Unknown token in buffer
GL2PS warning: Unknown token in buffer
GL2PS warning: Unknown token in buffer



-messages.
The number of warnings does not increase; I could simply select and copy the
gl2ps warnings from the terminal output w/o it scrolling out of sight.
The gl2ps warnings ignored the "more on" setting => that apparently doesn't
work on stderr.

In octave-4.0.1-rc1 generate-package-html worked fine, hence "regression" but
I didn't enter that tag as it relates to an OF package, not core Octave.

This occurs with OF-generate_html 0.1.9 and 0.1.10.

Perhaps related: during generate_package_html processing a figure was created
(probably from an xmlread.m or xmlwrite.m demo), and in octave-4.0.1-rc1 I get
warnings:

>> generate_package_html ("io", "io-html", "octave-forge")
[Fatal Error] oct-y7dX18.svg:3213:83: The value of attribute points"
associated with an element type "polyline" must not contain the '<'
character.
[java] org.xml.sax.SAXParseException; systemId:

type "polyline" must not contain the '<' character.

<RootNode created="04-Mar-2016">
    <TextChild useful="no" verbose="yes">These are text data</TextChild>
</RootNode>

>>

Whatever the cause, *if*  this is related, I think generate_package_html.m
shouldn't be hanging due to errors in code it is processing.
