Bug ID: 2932

but without a whitespace
Product: Exim
Version: 4.96
Hardware: x86
OS: All
Status: NEW
Severity: bug
Priority: medium
Component: Documentation

Fix doc for $run preexpand option and add examples.
I took some time for us to realise that the new *preexpand* option must be
appended to **run** without whitespace.
With an additional whitespace you'll instead receive the following error
message:
```
2022-11-09 17:16:39 H=(exim4) [127.0.0.1] temporarily rejected DATA: failed to
expand ACL string "${run ,preexpand{/usr/bin/printf "<%s> " $acl_m_arg1
$acl_m_arg2 $acl_m_arg3}}": missing '{' for command arg of run
```
```

expand ACL string "${run preexpand{/usr/bin/printf "<%s> " $acl_m_arg1
$acl_m_arg2 $acl_m_arg3}}": missing '{' for command arg of run
```
I've updated the docs and added examples that show the usage of the preexpand
option and point out the difference between run with and without the preexpand
option.
