Problem: test: trailing spaces used in tests
Solution: Rewrite tests to avoid trailing spaces (Paul Ollis).
Some tests currently rely on trailing whitespace at the end of lines,
escaped with '\'. I have demonstrated in another PR, such spaces can be
inadvertently removed and this is difficult to spot.
Note: there are more trailing spaces in a few more test files, see
testdir/test_codestyle.vim. Those are not yet removed.

Problem: Option handling for key:value suboptions is limited
Solution: Improve :set+=, :set-= and :set^= for options that use
"key:value" pairs (Hirohito Higashi)
For comma-separated options with P_COLON (e.g., diffopt, listchars,
fillchars), :set += -= ^= now processes each comma-separated item
individually instead of treating the whole value as a single string.
For :set += and :set ^=:
- A "key:value" item where the key already exists with a different value:
the old item is replaced.
- An exact duplicate item is left unchanged.
- A new item is appended (+=) or prepended (^=).
For :set -=:
- A "key:value" or "key:" item removes by key match regardless of value.
- A non-colon item removes by exact match.
This also handles multiple non-colon items (e.g., :set
diffopt-=filler,internal) by processing each item individually, making
the behavior order-independent.
Previously, :set += simply appended the value, causing duplicate keys to
accumulate.

Problem: 'listchars' "leadtab" not used in :list (after 9.2.0088).
Solution: Also check for "leadtab" when using :list. Fix memory leak on
E1572 if "multispace" or "leadmultispace" is set (zeertzjq).

Problem: "leadtab" behavior inconsistent on line with only TABs
(after 9.2.0088).
Solution: Don't consider those as leading TABs. Also add more tests for
existing behavior of "lead" and "leadmultispace" (zeertzjq).

Problem: cannot display tabs for indentation
Solution: Add the "leadtab" value to the 'listchars' option to
distinguish between tabs used for indentation and tabs used
for alignment (HarshK97).

Problem: 'listchars' "precedes" is not drawn on Tabs.
Solution: Only draw 'listchars' "precedes" when not skipping over cells.

Problem: No test for 'listchars' "precedes" with double-width char.

Cherry-pick test_listchars.vim changes from patch 9.0.0625.
Fix a regression from #30014 by moving the mb_schar assignment after the
double-width check.
Problem: too vague errors for 'listchars'/'fillchars'
Solution: Include the field name in error message.

Problem: Unused assignments when checking the value of 'listchars'.
Solution: Loop only once when just checking the value. Add a test to
check that this change doesn't cause double-free.

Problem: multispace wrong when scrolling horizontally
Solution: Update position in "multispace" or "leadmultispace" also in
skipped chars. Reorder conditions to be more consistent.

Oldtests clean up after themselves, and the options that need operators
to align with Vim all deny duplicates, so there is no need to set them
to default.
Also make the variable name that test_listchars.vim uses to align with
Vim more obvious.
