- * - Extend support for analog input data.
- * - Determine why analog samples of 'double' data type get scrambled
- * in sigrok-cli screen output. Is analog.encoding->unitsize not
- * handled properly? A sigrok-cli or libsigrok (src/output) issue?
- * - Reconsider the channel creation after format processing. Current
- * logic may "bleed" channel names into the analog group when logic
- * channels' columns follow analog columns (seen with "-,2a,x8").
- * Trying to sort it out, a naive change used to map logic channels'
- * data to incorrect bitmap positions. The whole channel numbering
- * needs reconsideration. Probably it's easiest to first create _all_
- * logic channels so that they have adjacent numbers starting at 0
- * (addressing logic bits), then all analog channels (again adjacent)
- * to simplify the calculation of their index in the sample set as
- * well as their sdi channel index from the "analog column index".
- * - Optionally get sample rate from timestamp column. Just best-effort
- * approach, not necessarily reliable. Users can always specify rates.
* - Add a test suite for input modules in general, and CSV in specific?
* Becomes more important with the multitude of options and their
* interaction. Could cover edge cases (BOM presence, line termination
* samplerates, etc).

+ * determination of an input file's format handler, then no options are
+ * in effect. Because specifying options requires selection of an input
+ * module to pass the options to, which obsoletes the format-match check.
+ *
+ * Which means that we only need to deal with the default format here,
+ * which happens to be the simple multi-column format without header
+ * lines or leading garbage. Which means that the check can be rather
+ * strict, resulting in high levels of confidence upon match, never
+ * "accidently" winning for unreadable or unsupported-by-default formats.
+ *
+ * This .format_match() logic only needs to become more involved when
+ * default option values change, or when automatic detection of column
+ * data types improves. Then the supported-by-default types of input
+ * data must be considered acceptable here in the format-match check
+ * as well.
+ *
+ * Notice that the format check cannot re-use regular processing logic
+ * when their implementation assumes proper input data and wll generate
+ * diagnostics for unexpected input data. Failure to match the format is
+ * non-fatal here, mismatch must remain silent. It's up to applications
+ * how large a chunk of data gets passed here (start of the file's
+ * content). But inspection of the first few hundred bytes will usually
+ * be GoodEnough(TM) for the format-match purpose. Notice that filenames
+ * need not necessarily be available to the format-match routine.
+ *
+ * This implementation errs on the safe side. Users can always select
