It is the user's responsibility to autoload bashcompinit. If we do it,
we may overwrite a custom complete function. If we don't do it at all,
it won't work out of the box.

This fixes debian bug
1111509, reported by Vincent Lefèvre.

Reported by Stephane Chazelas. Potentially sensitive arguments could
be leaked to the environment during completion computation.

… simplify logic. Update related test outputs and release notes.

Introduce new methods: `data()` to access buffer content, `empty()` to check buffer state, and `size()` to retrieve buffer size. Update unit tests to validate the behavior of these methods alongside existing functionality.

…g encryption and update related tests.

… shared helper retrieval, validation methods, and update usages across the codebase. Remove unused test coverage entries.

…king `validate()` for `names_dest` initialization

…or deterministic ID generation (fixes #1235).

cmake complains when building with -DZOPFLI-ON as opposed to =ON

qpdf permits replacing standard stream filters with user provided filters.
#1457 incorrectly removed that option.

Introduced explicit checks for empty streams and refined filtering conditions for improved clarity and correctness.

Fix QPDFFormFieldObjectHelper::getChoices (fixes #1433)

Add additional sanity check during xref recovery

Return the display value if the choices entry is an array of strings rather
than a single string.

Test file is need-appearances.pdf modified to contain one array entry.

Do not copy duplicate pages during xref recovery.

Thanks to github user @cdosborn for the basic enhancement.

Only top-level XMP metadata is supposed to be left unencrypted. All
other metadata is not treated specially.

Replace JetBrains-specific cmake profiles with CMakePresets.json

Plus sneak in some spell checks
