as far as I understand it, :ilist is supposed to be used for searching
for keywords like identifiers in a programming language. See the fourth
paragraph at ":help include-search".

With the slashes around the pattern you explicitly tell Vim to search
for only a part of a keyword, but without the slashes Vim searches for a
word (in Vim's sense of word, see ":help word") that is also a keyword.
Presumably, without looking at Vim's source code, a keyword must start
with a letter, so '20' would not be found.
