Not equivalent, this suggests that only those suffixes are recognized.
All the numerical options, if not specified otherwise, accept a string
representing a number as input, which may be followed by one of the SI
unit prefixes, for example 'K', 'M', 'G'.
"prefix" is favored over "suffix", because this is the term SI
prefixes are universally referenced to in the scientific/engineering

doc: avtools-common-opts: Fix terminology concerning metric prefixes
'k', 'M', and 'G' are SI (unit) prefixes or metric prefixes,
not 'number postfixes'. Also, the statement regarding binary
prefixes ("powers of 2 are used instead of powers of 10")
might be misinterpreted (1 kB = 10^3 B, but 1 KiB != 2^3 B).

About "binary suffixes", the correct term is "prefixes for binary
multiplies", see for example:
So I suggest something like:
If 'i' is appended to the SI unit prefix, the complete prefix must be
interpreted as a unit prefix for binary multiplies, which is based on
powers of 1024 instead of powers of 1000. ...
Unfortunately not still very clear, and a bit verbose, so feel free to
propose something better.
