Fix error messages containing format strings
The builtin primitive procedure `error` takes an optional message and
a list of arguments to include into the error message.
These args are formatted with `~S` and appended to the error message, so
that an example call of
`(error "Wrong argument: " 42)`
results in the output
"Wrong argument: 42"
If format strings occur in the message itself, however, they are
escaped. Thus a call like
`(error "Wrong argument: ~a" 42)`
is rendered as
"Wrong argument: ~a 42"
Some callers did not take this behavior into account, leading to
confusing error messages.
Changing the behavior of `error` to be
both backwards-compatible and accept also format strings inside messages
is not straightforward, because it would have to handle escaped `~`
characters as well. Therefore, fix `error` call sites using format
strings to use `format` before calling out to `error`.
The following files are affected:
* module/ice-9/format.scm (format)
* module/ice-9/r6rs-libraries.scm (resolve-r6rs-interface)
* module/oop/goops.scm (make)
* module/srfi/srfi-37.scm (Comment at the beginning of file)
* module/system/base/compile.scm (call-once)
* module/system/repl/command.scm (break, tracepoint)
* module/system/repl/common.scm (repl-default-options)
* module/system/vm/traps.scm (arg-check, trap-at-source-location)
There are a couple of further call sites that were left unchanged,
either because they are using their own `error` procedure:
* module/ice-9/read.scm
* module/ice-9/command-line.scm
or are not referenced from other modules:
* module/system/base/lalr.upstream.scm:
* module/sxml/upstream/assert.scm:
* module/sxml/sxml-match.ss:
