Web apps' "Export to Excel" often writes an HTML table and names it
.xls. GridCraft read such a file as CSV text, so it opened as lines of
markup in column A. Excel opens the table (after warning that the
format and the extension don't match).
Opening a file whose bytes are a web page with a table now reads the
first table as a sheet, through the clipboard HTML table reader: the
cells go through the CSV reader, so values read as they do in a CSV
(and stay text with csvAsText); <th> cells are bold and centred; the
sheet takes the page's <x:Name> or the file's name. A page that isn't
named .htm/.html opens with a warning saying what it is.

- clip_html: cap wildcard/glob lookback to a 12-byte window instead of scanning
outgoing text arbitrarily far for a semicolon (finding 18).
- print: wrap_lines binary-searches its break instead of rescanning the line
from the start for every band (finding 21).
- autofit: per-row merge index instead of scanning every merge per row during
autofit (finding 27) — behaviour covered by the existing autofit merge test.
- Save as Web Page: the used rectangle bounds the HTML (finding 28, #2387) —
a tall/wide or sparse far-right sheet now errors instead of growing
gigabytes of <td></td>.
- print: decode each embedded picture once per document instead of once per
band that shows it (finding 30).
Engine: 459 tests pass; clippy clean.
Clipboard HTML is read only as far as the pasted text's shape (clamped
to the sheet) and at most 1,000,000 cells; colspan/rowspan are clamped
to the sheet extent before expanding, and rowspan now keeps later rows
in their columns.

Spreadsheets put an HTML table next to the tab-separated text; Excel
(x:num) and LibreOffice Calc (sdval) record each cell's number there.
Paste now reads the HTML flavour (new paste_html host service, arboard on
desktop) and edit.paste takes an optional html param: a field that would
paste as text becomes the recorded number when the HTML cell shows the
same text, with an inferred format ("Rp"#,##0.00) that renders it back
identically.
