This comment expands all tabs using an 8-character tab-width. You
should ignore this commit when using git blame or use git blame -w.
In the early days, I used to use tabs where possible for indentation,
since emacs did this automatically. In recent years, I have switched
to only using spaces, which means qpdf source code has been a mixture
of spaces and tabs. I have avoided cleaning this up because of not
wanting gratuitous whitespaces change to cloud the output of git
blame, but I changed my mind after discussing with users who view qpdf
source code in editors/IDEs that have other tab widths by default and
in light of the fact that I am planning to start applying automatic
code formatting soon.
Change "-" to "--" for named parameters.
Remove spaces inside "[ option ]" for optional parameters.
Fix "pdf-mod-info --dump file" to match usage message.
New header qpdf/Types.h attempts to make sure size_t and off_t are
defined on any platform and in a way that would work with large file
support. Additionally, missing header files are included to get
unlink.
